BK's eternal money pit build - 1989 R32 GTR single turbo

[BK]

Well here we go again, time to FINALLY as promised start the GODZILR build thread that has been in progress, or shall we say "development hell" for 13 years now - THE MONEY PIT IS HERE !

For more info from the past and the bullshit I've been through with this car, start here

Which led to this

Then this happened....

 

The car has been a major pain in the arse for years. After many different setups and rebuilds, I've considered everything from selling it to burning it ! (Well I almost really did as above....). But I didn't. I decided if I'm going to keep it I may aswell go all the way with it, and get it to what I would consider to be a very well rounded street / drag / track setup.

Maybe there is light at the end of the tunnel now, as it is finally properly alive and running in the new engine as we speak.

I have now done 20km and counting....

[BK]

I'm working away at the moment and bored, so I have time to mention the current build details completed as of 1st of Feb. 2020. June 2021

I think that's about it from what I can remember right now ? 😔

[boomtheroom]

whats build cost so far?

[BK]

Geez well, on this latest incarnation, which I call build 5 on this car I really haven't calculated it yet - but it's a lot. I have a folder that is 3 inches thick that I am going to go through one day. Off the top of my head though $30k for example has gone into just the latest short motor and transmission, but annoyingly that's just I drop in the ocean for this car really. Lets just say the count is six figures since purchase....

This cars spec has always been very fluid, so nothing has ever really stayed the same. 3 different ECU setups, at least 6 different gearbox combinations, 5 different clutch combinations, 3 different blocks, 5 different forged bottom ends including 2 x Nitto 2.8s, never ending fuel pump changes, nearly burning the car down from engine loom melting - the list is endless with changes and failures and it all adds up. Yeah it's been tiring and frustrating, but I think I might have finally got this thing to the vision I imagined for the car.

I do have some updates for this car I have to get around to mentioning when I go through my photos, like I finally got to piss my aging Falkens off end of April and get some new AD08R goodness.

[BK]

Been wanting to try these for ages....

 

[BK]

Been trying to find the time to actually work on my own cars. Got a few things done recently like actually fitted the ARD 150 amp alternator. Got round to replacing the Nismo 1.3bar radiator cap in the PWR radiator to a proper Stant 16psi lever cap as recommended by PWR.

Removed the brand new AD08R yokies from the GT1 wheels and replaced them with new Hankook RS4. Big reason is I think the 265 AD08 seemed just a tad too big, the 265 RS4 is noticeably narrower from sidewall to tread and fit better. The AD08s went onto my R33 TE37s to replace the very aged V103s so they weren't wasted and fit a lot nicer to that car.

So today I'm off to tackle finally installing the Ross crank trigger kit that I got about 18 months ago. Never done one before but hopefully this will be pretty straightforward.

 

Also found a couple of pics of when the Precision 6466 went in to replace the ageing HKS. Went from this:

 

To this:

 

 

[Shoota_77]

Wow, it certainly has been a mission!  You've thrown some serious parts at it!  Must be an absolute beast to drive?

 

[BK]

Yes it's always been a wicked to drive car, with very wicked breakages to go with it. Power delivery was like a light switch before when it was running 10s. This time around so far, so good - everything feels as it should. Handles good, very progressive off boost and the dog box operates well.

I am still yet to really lean on the car in kill mode as it hasn't seen a dyno since the 6466 has gone on. Making sure all the bugs are ironed out first. All tuning so far has been done by myself on the elite. That's why I thought I better pull my finger out and fit the rest of the trigger kit so I get it running on E85 (just need more tuning) and can turn the wick up. Found the rest of my trigger kit finally

 

[mr_rbman]

Interesting you say the AD08's appeared wider...

I have some 265 x 35 AD08's and I get scrubbing yet my other wheels with 275 x 35 NT01's nothing...

Admittedly there is 10mm difference in offset but I never thought the actual tyre width may vary, mmmmm...

[BK]

Yep the Advan AD08R in 265/35R18 was even wider than the Advan V103 in 275/35R18. I found a comment somewhere online that someone was complaining that the RS4 Hankooks in 265 was narrower than AD08R, and if so that would fit nicer for me. So I looked up the difference and sure enough the sidewall was nearly the same but the tread area on the RS4 was definitely 10mm narrower - both 265. So I went for those and they are definitely much nicer. No scrubbing at a ride height of about 355mm and camber at -1.0 front and -1.25 rear (I think). As mentioned above at least I just put the 265 AD08Rs on the 33 GTR so they were not wasted.

Really the correct AD08R should be 255 on a 32. I know now what to use for AD08R on 18" and will be sticking with:

R32 GTR - 255

R33 GTR - 265

[BK]

Some pics of what used to be on the car when I was first building it. Wow, how things change...like some of these photos before smart phones existed.

Sard fuel pressure reg and Sard 660cc injectors

Apexi Power FC PRO with ignition cut and launch control - WOW !

My first Trust 6 speed straight cut dog engagement transmission because...

this happened to the standard gear GTR gearbox then....

 

this happened to the Trust 6 speed straight cut dogbox anyway 🤦‍♂️ This was 3rd from memory.

 

An OS Giken 5 speed replaced these and amazingly I did not break that, even drag racing. But I did feel the ratios of the OS giken box to be not so suited to the HKS turbo fitted at the time, and it was also a helical / synchro box. So I sold that OS giken 5 speed while it was in good condition so I could....

 

that's right, go and buy another Trust 6 speed. Again ! 🤦‍♂️ Don't have pictures of this one busted as these pictures above are actually after 3rd and 4th have been replaced. Between buying, destroying and repairing 2 x Trust boxes and 1 x OS giken 5 speed gearset running just on this car, I'd definitely spent more than just originally purchasing a sequential like an OS-88 or a Holinger.

But I'm stubborn and want my straight cut H pattern dog, which basically came down to PPG or PAR really being the only ones doing what I want.

PAR eventually got the nod over the PPG for two reasons.

1. PAR has optional billet interlock shift barrel

(PPG makes you use the factory sintered one)

2. PAR I could choose to have synchro + helical 5th with 1st - 4th straight cut dogs.

(PPG 1st -5th straight cut dog only)

If I could have optioned the above with PPG I most likely would have went the Pfitzner route as the price difference was negligible. Bolted it to a modified 10 plate transfer case and the gearset assembled on OS giken billet centre plate with GM 28.5mm, 26 spline input shaft.

This box is still intact.

So far.

[BK]

Managed to get a few more things done on it in between working on the other 32. Got some more road tuning done and realised the speed reading in the Elite was way out. Standard pulses per km was around 2450, which was giving me about an indicated speed of around 30km/h when doing about 60 -70km/h. Changed it to about 1200 pulses per km and seems to have corrected it to very close to the factory dash. I'll do another calibration next time with a GPS to get an exact pulse count to get it exact.

One thing that annoys me no end is the R32 radiator recovery bottle and washer bottles always destroy themselves from years of heat. I've replaced them before but now they are a Nismo heritage item they are about $350 - $400 per washer or coolant bottle - and the bastards don't even come with caps ! After much digging the Jap company Garage active do an aftermarket replacement 32 set at about $450 for the pair. They are constructed a lot more solidly and thicker than the factory items and even comes with caps and washer motors. While I was down there I replaced a few random clips, replaced the headlight chassis rubbers and threw in a new factory battery tray.

 

 

Also found a few of the old dyno sheets for blue 32 from about 10 - 11 years ago when I was running a 2.6 and the HKS turbo. All runs were on 98 except the blue trace on the Willall mainline which was on VP 109 unleaded. Yeah it made power before but was disappointingly only good for 10s. Note the Willall runs were done on the 2nd 2.6 motor with Arias 7.0 low comp pistons and the Dyno dynamics done on my 3rd 2.6 build in this car with 9.0 comp CP pistons and new balanced long nose crank.

 

Also finished the Ross full crank trigger kit install and configuration which I'll shed some more light on at a later date.

Hey BK,

Is this the washer bottle set you are referring to?

Yeah only about 3% of them had it. The old man didn't believe it was a factory colour at first. Dude when I finally hit the dyno this year if it punches out what your 6466 does I'll be more than satisfied.

On another note of completely random observation, I was in the Platinum racing site looking at random stuff and noticed they are now an agent for PAR engineering. 

Had a look at the straight cut dog box gearset and thought the photo looked familiar on their site:

 

Definitely seen it somewhere before.....

2.8 and a 6466 seems to be a good combo

 

My engine is apart at the moment getting rings and bearings, Head has been CNC and shimless by RAMS and a new plasmaman intake manifold and intercooler for good measure.

Keen to see how much more mph we can get out of the 6466

have they put the new technology into the 6766 yet? my understanding the 6466 is still the better turbo. i was going to go the 6766 and was talked out of it by a few members sayings makes same power with less response.
